DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0037] Please refer to Figures 1 to 10 A center of gravity adjustable scraper comprises a vehicle body 2, a moving unit 1 and a working assembly 3 arranged on the vehicle body 2, a cab 4 fixedly connected to the vehicle body 2, and a bucket 5 connected to the working assembly 3. The working assembly 3 is a hydraulic system, which can drive the bucket 5 to overturn, so that the bucket 5 can realize the actions of loading and unloading. An opening and a pipeline slot 52 are arranged on one side of the bucket 5, and a discharging flap 51 is rotatably connected in the opening.

[0038] A pushing unit 6 is connected to the inside of the bucket 5, and the pushing unit 6 comprises a loading seat 61 slidably connected to the inner wall of the bucket 5 at both ends, a lower pushing plate 62 rotatably connected to the upper end of the loading seat 61, an upper pushing plate 63 rotatably connected to the other end of the lower pushing plate 62, and a pushing driving part 64 located in the inside of the bucket 5 and connected to the loading seat 61. The other end of the upper pushing plate 63 is rotatably connected to the inner wall of the bucket 5.

[0039] The pushing driving part 64 comprises a hydraulic rod one 641 rotatably connected to the inner wall of the bucket 5 at one end, and a pushing unit 6 connected to the inner wall of the bucket 5 at one end and connected to the loading seat 61 at the other end. The telescopic end of the hydraulic rod one 641 is connected to the pushing unit 6.

[0040] The lower end of the vehicle body 2 is further connected to a hydraulic counterweight assembly.

[0041] The pushing unit 6 comprises a connecting plate one 642 rotatably connected to the inner wall of the bucket 5 at one end, a connecting plate two 643 rotatably connected to the other end of the connecting plate one 642, a sliding groove one 644 arranged on one side of the connecting plate one 642, and a sliding seat one 645 slidably connected in the sliding groove one 644. The other end of the connecting plate two 643 is rotatably connected to one side of the loading seat 61. The telescopic end of the hydraulic rod one 641 is rotatably connected to the sliding seat one 645.

[0042] By adopting the technical scheme, in use, the oil supply pipeline of the hydraulic system of the shovel loader can pass through the pipeline slot 52 into the bucket 5 and be connected with the hydraulic rod one 641. When the bucket 5 is overturned to unload, the hydraulic rod one 641 extends to push the sliding seat one 645 to move in the sliding groove one 644, and the hydraulic rod one 641 can also push the connecting plate one 642 to rotate. The rotation of the connecting plate one 642 pushes the shovel material seat 61 to move inside the bucket 5 through the connecting plate two 643. The shovel material seat 61 can shovel the material on the bottom wall inside the bucket 5. When the shovel material seat 61 moves, it can also drive the lower pushing plate 62 to move. The movement of the lower pushing plate 62 drives the upper pushing plate 63 to rotate, so that the lower pushing plate 62 and the upper pushing plate 63 move. The rotation of the lower pushing plate 62 and the upper pushing plate 63 can directly push the material inside the bucket 5 from back to front, so that the material is moved out of the bucket 5, the arch bridge and the suspension phenomenon of the material are broken, the material falls as a whole and is discharged, most of the material can be pushed out in one complete stroke, cross contamination is reduced, loading rate is improved, unloading time is greatly shortened, and unloading efficiency is improved.

By rotating to open the unloading flap 51, the material entering the rear of the lower pushing plate 62 and the shovel material seat 61 can be discharged from the opening of the bucket 5.

[0043] As shown in Figure 10 and Figure 11 , the hydraulic counterweight assembly comprises a liquid storage part two 16 fixed to the left side of the lower end of the vehicle body 2, a liquid storage part one 14 fixed to the right side of the lower end of the vehicle body 2, and a hydraulic liquid delivery part 15, and the hydraulic liquid delivery part 15 is connected with the liquid storage part one 14 and the liquid storage part two 16.

[0044] The liquid storage part one 14 and the liquid storage part two 16 are both provided with a plurality of wave prevention plates inside. The plurality of wave prevention plates are designed to avoid the liquid inside the liquid storage part one 14 and the liquid storage part two 16 from shaking when the vehicle body 2 moves. The design of the wave prevention plates is the same as that of the wave prevention plates in the existing oil tanker, which is mature prior art and will not be described here. At the same time, the liquid storage part one 14 and the liquid storage part two 16 are both provided with liquid level sensors inside, and an inertial measurement unit (IMU) is also installed on the vehicle body 2 to monitor the pitch and roll angles of the vehicle body as an auxiliary control signal.

[0045] By adopting the technical scheme, when the bucket 5 is empty, the liquid (hydraulic oil or water) in the liquid storage part one 14 is sent into the liquid storage part two 16 through the hydraulic liquid delivery part 15, so that the force on the front wheels is increased and the grip is improved. When the bucket 5 is full, the liquid (hydraulic oil or water) in the liquid storage part two 16 is sent into the liquid storage part one 14 through the hydraulic liquid delivery part 15, so that the force on the rear wheels is increased to offset the uneven power caused by the rear movement of the center of gravity. By changing the position of the liquid mass, the downward pressure of the front and rear wheels is adjusted to make the grip more balanced.

[0046] The hydraulic delivery part 15 adopts the design of pump body + reversing valve + check valve, and is also equipped with a controller, which receives the signal of the inertial measurement unit and controls the pump body and the reversing valve to work according to the preset logic algorithm; the way of alternating delivery of such liquid between the front and rear two chambers to adjust the center of gravity belongs to the mature prior art, for example, ships need to transfer seawater between left and right, front and rear cabins by pumping to realize the adjustment of the trim or list of the ship and ensure the stability during sailing; therefore, the specific structure and principle of the hydraulic counterweight assembly are not explained in detail here.

[0048] By adopting the above technical scheme, when the hydraulic rod one 64 works, the hydraulic rod two 74 works, and the hydraulic rod two 74 extends to push the lower pushing plate 62 to move towards the opening of the bucket 5, and the hydraulic rod two 74 can also push the sliding seat two 72 to slide in the chute two 71; when the bucket 5 is scooping and loading materials, the hydraulic rod two 74 can support the lower pushing plate 62, ensuring the stability of the pushing unit 6 when loading materials in the bucket 5; when the pushing driving part 64 pushes the scooping seat 61 to move for pushing, the sliding seat two 72 and the lower pushing plate 62 are pushed by the hydraulic rod two 74 to move, so as to apply force to the lower pushing plate 62 and support the lower pushing plate 62 for pushing, ensuring the stability of the lower pushing plate 62 during the pushing process.

[0049] As shown in Figures 5-7 , the inner wall of the chute two 71 is fixedly connected with a rack 81, the sliding seat two 72 is connected with a vibration and material removing unit 8 on one side, and the vibration and material removing unit 8 comprises a movable groove one 82 opened in the sliding seat two 72 for accommodating the rack 81, a gear one 83 rotatably connected in the movable groove one 82 and engaged with the rack 81, two flanges 84 integrally formed on one side of the sliding seat two 72, a gear two 85 rotatably connected at both ends of the two flanges 84 and engaged with the gear one 83, two ratchets 86 and an incomplete gear 87 rotatably connected on one side of the two flanges 84 respectively, and a vibration part 88 connected on one side of the two flanges 84 respectively, both ends of the gear two 85 penetrate through the two flanges 84 and are fixedly connected with the two ratchets 86.

[0050] The vibration applying part 88 comprises a vertical plate 881 integrally formed on one side of the flange 84, a guide rod 882 fixed at two ends with the vertical plate 881 and the sliding seat 272 respectively, a counterweight 884 slidingly connected on one side of the flange 84 and movably sleeved on the outside of the guide rod 882, a gear slot 885 opened on one side of the counterweight 884, and a spring 883 sleeved on the outside of the guide rod 882, and two ends of the spring 883 are connected with the counterweight 884 and the vertical plate 881 respectively.
